17 Display Module Usage SCROLLING MARQUEE DISPLAY — T his device is the keypad interface used for acces sing unit in f ormation, reading sensor values, and testing the unit. See Fig. 18. The scrolling marquee display is a 4-key , 4-character , 16-segment LED (light-emitting diode) display .
18 Adjusting the Contrast — The contrast of the display can be adjusted to suit ambient conditions. T o adjust the contrast of the Navigator module, press the key until the dis- play reads, “Select a menu ite m.” Using the arrow keys move to the Configuration mode.
19 Table 3 — Thermistor Designations Table 4 — Switch Inputs Compressor Expansion Module (CXB) — The CXB is only used on unit sizes 070-100 to provide additional inputs and outputs for fans and compressors when the unit has more than 4 compressors.
20 Carrier Comfort Network ® (CCN) Interface — The 38AP units can be connected to the CCN if desired. The communication bus wiring is a shielded, 3-conductor cable with drain wire and is supplied and installed in the field. See T able 5. The system elements are connected to the communi- cation bus in a daisy chain arrangement.
21 SUPPL Y AIR TEMPERA TU RE (SA T) ACCESSOR Y (33ZCSENSA T) — A supply ai r temperature sensor i s required for unit sizes 040-100 and all units equipped with the digital scroll option. The SA T sensor consists of a thermistor encased within a stainless ste el probe.
22 Units on the CCN can be monitored from the space using the RJ1 1 connector provided with the space sensor, if desired. T o wire the RJ1 1 connector into the CCN (Fig. 26): 1. Cut the CCN wire and strip ends of the red (+), white (ground), and black (–) conductors.
23 Fan Statu s Input — A proof-of-fan operation is recom- mended and needs to be field installed in the indoor unit. Sev- eral different types of swit ches can be utilized, such as a differ - ential pressure switch located acr oss the indoor fan or auxiliary contacts on an indoor fan contactor .
24 • C.TYP = 3 (TST A T -MUL TI) configuration will fo rce the MBB to monitor the therm ostat inputs to make a determination of mode. Unlike traditional 2-stage ther- mostat control, the u nit is allowed to use m ultiple stages of cooling control and perform V A V style operation.

28 Service T est — Both main power and contr ol cir cuit power must be on . The Service T est function shoul d be used to verify proper operation of condenser fan(s), compressors, minimum load valve solenoid (if installed), liquid line solenoid valve (if installed), and remote alarm re lay .
29 CHIL_S_S variable is 'Stop.' Similarly , the control mode will be 6 when the CHIL_S_S variable is 'S tart.' Set P oint Adjustment CV SET POINT ADJUSTMENT — I f th e un it i s con fi gu re d for control type SPT MUL TI ( C.TYP =5) and the Space T em- perature Offset Sens or is enabled.
30 Table 10 — 4 to 20 mA Reset NO TE: T he e xample abov e shows how to configure the unit f or 4 to 20 mA reset. No reset will occur at 4.0 mA input, and a 5.0 F reset will occur at 20.0 mA. An energy management module is required. Table 11 — Configuring Outdoo r Air and Space Temperature Rese t * 1 item skipped in this example.
31 Demand Limit — Demand Limit is a feature that allows the unit capacity to be limited during periods of peak energy usage. There are 3 types of demand limiting that can be configured. The first type is through 2-stage switch control, which will reduce the maximum capacity to 2 user-configu- rable percentages.
32 DEMAND LIMIT (CCN Loadshed Controlled) — T o co n- figure Demand Limit for CCN Loadshed control, set the De- mand Limit Select ( Configuration RSET DMDC ) to 3. Then configure the Loadshed Group Number ( Configura- tion RSET SHNM ), Loadshed Demand Delta ( Configu- ration RSET SHDL ), and Maximum Loadshed T ime ( Configuration RSET SHTM ).
33 PRE-ST ART -UP Do not attempt to start the air -conditioning system until the following checks have been completed. System Chec k 1. Check all system components, including the air-handling equipment. Consult manufacturer's instructions. If the unit has field-installed accessor ies, be sure all are proper- ly installed and wired correctly .

47 Check Com pressor Oil Level — After adjusting the refrigerant charge, allow each circuit to run fully loaded for 20 minutes. Stop the compressors and check the oil level. Oil level should be 1 / 8 to 3 / 8 up on the sight glass. Add oil only if necessary to bring the oil into view in the sight glass.
48 2. Fan status switch input should close. Note the unit will not start unless the fan status input is closed. 3. Close Y1 input unit will stage up to 50 % capacity with 1 minute between stages. 4. Close Y2 input the unit will stage up to 100% capacity with 1 minute between stages.
49 For all units, if temperature rese t is used, the unit controls to a higher leaving temperature as the building load reduces . If demand limit is used, the unit may temporarily be unable to maintain the desired leaving- air temperature because of im- posed power limitations.

60 Every month: • Check condenser coils for debris , clean as necessary . • Check moisture indicating sig ht glass for possible refrig- erant loss and presence of moisture. Every 3 months: • Check refrigerant char ge. • Check all refrigerant joints and valves for refrigerant leaks, repair as necessary .
61 Advanced scroll temperature protection is a form of internal discharge temperature protection that unloads the scroll com- pressor when the internal temperature reaches approximately 300 F . At this temperature, an internal bi-metal disk valve opens and causes the scroll elemen ts to separate, which stops compression.
